Sample managed care purchasing specifications related to primary and secondary prevention and medical management of HIV/AIDS. The specifications are intended for use in Purchasing Agreements that either for a preset fee (i.e., a premium) or under an administrative services only (ASO) agreement for the delivery of comprehensive health care through a network of participating providers. These specifications have been developed for use by both public sector Purchasers (e.g., state Medicaid programs) and private-sector entities (e.g., employers and employer purchasing coalitions).
